class: RecMutex

[19:7] extends: object

The GRecMutex struct is an opaque data structure to represent a recursive mutex. It is similar to a #GMutex with the difference that it is possible to lock a GRecMutex multiple times in the same thread without deadlock. When doing so, care has to be taken to unlock the recursive mutex as often as it has been locked. If a #GRecMutex is allocated in static storage then it can be used without initialisation. Otherwise, you should call g_rec_mutex_init() on it and g_rec_mutex_clear() when done. A GRecMutex should only be accessed with the g_rec_mutex_ functions.

Methods

• RecMutex (Handle = null)

  Creates a new RecMutex by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.
